    testsuite, x86: Add dg-requires for assemble/run tests using AVX512.
    
    These fail on most Darwin targets because they require either assembler
    or runtime support.  For 32b Darwin add -mdynamic-no-pc to compile cases
    to better match the codegen of ELF targets.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/i386/avx2-shiftqihi-constant-2.c: Require AVX512.
            * gcc.target/i386/pr104704-1.c: Likewise.
            * gcc.target/i386/pr104704-4.c: Likewise.
            * gcc.target/i386/pr110227.c: Likewise.
            * gcc.target/i386/vect-pr115895.c: Likewise.
            * gcc.target/i386/avx512fp16-pr101846.c: Add mdynmic-no-pic
            for 32b Darwin.
            * gcc.target/i386/pr101796-1.c: Likewise.
            * gcc.target/i386/pr101846-2.c: Likewise.
